Google hasn't addressed this as far as I can tell, and they say that for some ad units, they'll display a more mobile friendly ad themselves when they detect a mobile user.
But that doesn't get around the issue of the big square/rectangles. IF you are viewing on a touch screen such as an iPhone, which has a 320x480 display, typically in portrait mode, and a 300x250 ad is shown, there's a significantly higher risk of an accidental click, because it's almost impossible to avoid the ad when swiping down. Now as far as I know, only the LINKS are clickable, but it's still (to my mind) a potential issue.
As far as closing accounts - I don't think it's likely either, but it's *possible*. I dunno how many times I gotta keep saying this - IT DOESN'T MATTER IF YOU DID ANYTHING WRONG OR NOT. If your ad serving, or your traffic presents a significant risk to advertisers (WHETHER OR NOT YOU DID ANYTHING INTENTIONALLY) you are at risk of being shut down.
That's why I took the AdSense off first thing when my bot attack started. I didn't create the attack, I'm trying like heck to stop it, but if I kept serving ads to it and something went wrong, it wouldn't matter.
(And for what it's worth, I agree with Google on that - as an advertiser, I don't want to pay for bogus clicks, no matter whose fault they are)
